FCRCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 340,277, dated April 20, 1886.

Application filed October 2, 1885. Serial K01185 138. (No model.)

To all whom it may concern:

Be it known that I, JABEZ W. BRAMLEY, a citizen of the United States, residing at the city of Lockport, in the county of Niagara and State of New York, have invented a new. and useful Improvement in, Force-Pumps, of which the following is a specification.

My invention relates to pumps, and is an improvement in hand and power pumps for steam or water. 1

The objects of the invention are to improve the construction of the air-chamber and of the cross-head, and to provide a pump which may be easily converted either from a hand to a power pump or from a power to a hand pump.

The invention and improvements consist in the construction and combination of the several parts herein set forth.

In the accompanying drawings, Figures 1 and 2 are sectional views of the pump with a portion of its valve-chamber broken away. Fig. 3 is a sectional view of a portion of the air-chamber and guide-plate. Figs. 4 and 5 are enlarged views of the cross-head and handle, and Figs. 6 and 7, on Sheet 2, are sectional views of a steam pump provided with my improved air-chamber, and Fig 8 is a sectional View of the chamber itself.

In the drawings like letters refer to corresponding parts.

A represents the airchamber; B, the crosshead; 0, the link-connection; l), piston-rod; E and E, ears or lugs to support cross-head; F, the guide-plate; G, stuffing-box; H, 1e

ver or handle; K, the valve chamber of the pump, and X the steam-cylinder.

The air-chamber is cast hollow and with a dent slot or opening in one side, (see Figs. 1 and 7,) designed for the reception of the piston-rod, cross head, and their connecting mechanism, and on either side of this opening in the air-chamber, and extending outwardly therefrom, are lugs or ears E E, designed as a fulcrum or support for thelever or cross-head.

The cross-head Bhas three ways or openings for thehandle orleverH-viz., one at the end, (see Fig. 1,) and one on the upper side, (see Fig. 4,) and one on the lower side, these last two being formed by an opening on either side, and extending entirely through the crosshead from one side to the other.

The mode of connecting the cross -head to Heretofore pumps have been constructed.

with pear-shaped air-chambers, but without slots or openings therein. Such a construction necessitates the locating of the chamber at the side of the piston or plunger rod, instead of above it. This involves expense and trouble in forming the offset necessary for connecting with and supporting the air-chamber. Then, too, the friction of the rod has heretofore fell entirely upon the stuffing-box G and gland. Now, by forming the air-chamber with an opening or slot therein I save this extra expense and trouble attendant upon constructing the necessary offset, and, besides, I am enabled to locate the air-chamber directly and vertically above the valve-chamber, and by lengthening the pistonrod and passing it through the guide-plate G, I am enabled to maintain the rod always in a vertical line with the valve-chamber, thereby almost entirely relieving the stuffing-box and gland from the objectionable friction. Then,too,if I desire to use the pump in connection with a windmill or other power as a power-pump, I have only to remove the cross-head and connectinglink and connect to the rod above the guideplate; and for steam-pumps the connection may be as shown by Sheet 2.

\Vhen using the pump as a hand-pump, if its location in the house is such that the handlever II would be in the way in the position shown in Fig. 1, my new cross-head enables the operator to place the lever in an upright position, as shown in the same figure and by dotted lines. If this last position would bring the handle too high, it may be inserted from the bottom oftlie cross-head, as indicated by other dotted lines in the same figure. Then, too, my manner of constructing and connecting the air-chamber with the pump facilitates the removal of either for repairs; besides, by giving the air-chamber a half-turn either to the right or left, the pump is changed from a 2. As an article of manufacture, the herein :5

shown and described air-chamber A, provided with a slot therein, whereby the placing of an air-chamber directly over or in line with a valve-chamber is made possible, and the necessity of providing an offset therefor is obviated, 20

substantially as described.
